3 Claims. 1

The present invention relates to new and useful improvements in shingles designed for use as a roofing or siding shingle and more particularly to interlocking means for adjacent shingles to effectively seal the edges thereof.

An important object of the present invention is to provide an interlocking shingle of this character which may be constructed of metal or other suitable material, and in which the edges of adjacent shingles are provided for interlocking en gagement to secure the shingles in assembled relation against any possibility of becoming separated from each other or from the structure to which the shingles are attached.

A further object of the invention is to provide a roofing or siding shingle having the edges thereof formed with interlocking flanges arranged to cover the nails or other fastening devices employed for securing the shingles to a roof or wall siding and thus prevent any possibility of the nails from working loose as Well as to conceal the heads of the nails.

A further object is to provide an article of this character of simple and practical construction, which is eflicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a plan view showing a group of the shingles connected in assembled relation and with parts broken away and shown in section;

Figure 2 is a fragmentary sectional view taken on the line 2--2 of Figure 1;

Figure 3 is a perspective view of one of the shingles;

Figure 4 is a fragmentary plan view showing the shingles applied to the corner of a roof Figure 5 is a sectional view taken on the line 5-5 of Figure 4;

Figure 6 is a perspective view of one of the starting shingles for the vertical edge of the roof; and

Figure 7 is a similar view of one of the starting shingles for the lower horizontal edge of the roof.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the present invention, the numeral 5 designates the shingle generally and which is constructed of sheet metal or other suitable material, the shingle being of substantially square-shape to provide right angular side edges.

A pair of adjacent side edges of the shingle are bent inwardly upon the outer surface of the shingle to provide flanges 6, the adjacent ends of the flanges at one corner of the shingle being mitered as shown at I to seal said corner of the shingle.

The remaining edges of th shingle are bent inwardly at the underside of the shingle to provide flanges 8 which likewise have their adjacent ends mitered as shown at 9 to seal the meeting edges of the flanges 8 at a corner of the shingle diametrically opposite from the meeting ends of the flanges 6. The flanges 8 are of a width substantially greater than the flanges 6 and are adapted for interlocking engagement with the flanges of adjacent shingles when the shingles are placed in overlapping relation one upon the other as shown in Figure 1 of the drawings.

Openings H) are provided in the shingles slightly inwardly from the edges of the flanges 6 to receive nails or other fastening devices H for attaching the shingle in assembled interlocking engagement to a roof l2, or to a siding or other building structure, the heads of the nails being concealed under the wider flanges 8 as shown in Figure 1 of the drawings whereby to prevent the nails from working loose from the roof or other supporting structure.

The corners of the shingles at the junction of the flanges 6 and 8 are cut at an angle of 45 degrees with respect to the adjacent edges of the shingle as shown at 13 and the adjacent ends of the flanges 6 and B are likewise cut at a corresponding angle so that the free ends of the flanges 6 and 8 lie in the plane of the corners l3 of the shingle. The corners l3 of adjacent shingles meet in edgewise abutting relation when the shingles are secured in assembled relation to a roof or siding with the corner of the flanges 6 uppermost and with the corner of the flanges 8 lowermost and with the corners i3 positioned perpendicularly as shown in Figure 1 of the drawings. The free ends of the flanges '6 and 8 of adjacent shingles thus abut with a mitered joint as shown at M to thus seal the free ends: of the flanges at the meeting corners l3 of the shingle.

In Figures 6 and '7 of the drawings, I have illustrated starting shingles I 5 and [6 for the vertical side edges and the lower horizontal edges respectively of a roof, the starting shingle l5 for the side edges ofthe roof being constructed of half of one of the main roof shingles 5 to include a straight vertical edge [1 which is positioned flush with the side edge of the roof and an upper relatively narrow flange I8 which extends downwardly at the front of the shingle and a lower relatively wide flange [9 at the rear of the shingle, the flanges I8 and i9 interlocking with the flanges of adjacent shingles in the manner as heretofore described. The opposite vertical edge 20 of the shingle [5 which is parallel to the edge ll abuts the corresponding corner of an adjacent shingle 5.

The starting shingle M5 for the lower horizontal edge of the roof is constructed similar to the top half of one of the shingles 5 and includes the upper relatively narrow flanges 2| overlying, the front of the shingle and meeting at the upper corner thereof with a mitered edge 22. The side edges 23 below the flanges are parallel and the bottom edge is bent rearwardly at right angles to form a flange 24 which is attached to the bottom edge of the roof 42 as shownin Figure .5. The flanges 2| interlock with the lower flanges 8 of adjacent upper shinglesii or with the flange iiiof one of the vertical starting shingles l5.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to i be understood, however, that even though there is herein shown and described a preferred embodimentoi' the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

What I claim is:

1. A roofing shingle comprising a flat body of predetermined shape, relatively narrow and wide flanges at pairs'of top. and bottom edges of. the body and overlying the opposite surfaces of the body, said body having openings adjacent to and spaced downwardly of the narrow flanges for receiving fastening devices, said narrow and wide flanges being adapted for interlooking engagement with wide and narrow flanges of adjacent shingles and with the wide flanges of an adjacent shingle covering said fastening devices.

2-. A roofing shingle comprisinga flat, substantially-square-shaped body positioned on a supporting structure to provide pairs of upper and lower edges, relatively narrow flangesat the pair of upper edges overlying the top surface of the 4 body, the adjacent ends of said flanges being mitered to abut each other at the upper corner of the shingles, relatively wide flanges at the pair of lower edges of the body and underlying the bottom surface of the body, the adjacent ends of said wide flanges also being mitered to abut each other at the lower corner of the shingle, said narrow flanges adapted for interlocking engagement with the wide flanges of an adjacent shingle and said body having openings adjacent to and spaced downwardly of the narrow flanges for receiving fastening devices and to be covered by the wide flanges, the remaining corners of the body at the sides of the shingle having vertical straight edges and the ends of the narrow and wide flanges adjacent the straight edges terminating in 'the'plane of said straight edges.

3. In a roof construction composed of overlapping shingles and including starting shingles at the lower edge of the roof and each having a rearwardly projecting horizontal flange at its lower edge underlying the lower edge of the roof, and said-starting shingles also having an inverted V-shaped upper edge formed with an interlocking channel on the front surface of the shingle and openings adjacent to and below said channel for receiving fastening devices, and main shingles having V-shaped lower edges and inverted V- shaped upper edges each formed with interlocking channels, said upper channels being formed on the front surface of the shingles and said lower channels being formed on the'rear surface of the shingles and having interlocking engagement with the upper channel of the starting shingles, and saidloweredge of the main shingles overlapping and covering theopenings and fastening devices of said starting shingles.
